Andrew Tridgell 0141ec5be7 AP_AHRS: fixed switching airspeed sensor based on EKF3 affinity 
we need to use the EKF selected airspeed sensor when the EKF is setup
to run a different sensor on each lane

Andrew Tridgell 01fb16b3b0 AP_AHRS: relax arming checks for inactive AHRS types 
When using an EKF as ride-along we should not fail arming if it has
inconsistent yaw between its lanes. This is especially important when
using external yaw or GPS yaw with EKF3, where yaw is expected to be
bad with EKF2.

The check on DCM is based on the existance of an AHRS view. This is so
that tailsitters do not get arming failures due to the inability of
DCM to cope with being nose up

Peter Barker 29d2eed9e4 Sub: view update does not take skip_ins_update 2021-08-31 14:28:53 +10:00
Peter Barker 9dbd9d1e06 AP_AHRS: call INS update in AP_AHRS::update w/o holding data sem 
We shouldn't be holding the data semaphore while waiting for the samples
- lots of things might be unnecessarily blocked

DCM's update function doesn't need to take the semaphore as it is
already taken by AP_AHRS

Peter Barker a933652950 AP_AHRS: return perfect airspeed estimate for EKF-type 10 
... rather than the EKF3 estimate
 2021-08-25 18:28:12 +10:00
Andrew Tridgell 53e7436525 AP_AHRS: allow for fallback to DCM in quadplanes 
this adds the necessary functions to allow for flying a quadplane on
DCM as an emergency fallback. It sets the NavGainScalar to 0.5 to
reduce the VTOL controller gains to allow planes to cope with the
higher lag of DCM
 2021-08-19 14:42:28 +10:00

Peter Barker 29aed55a74 AP_AHRS: remove pointless zeroing of gyro_estimate vector 
This value is assigned to in the following "if" block in both the for
and against cases, and isn't used to determine the new value.
 2021-08-12 08:52:24 +10:00
Peter Barker 73bad9fd2d AP_AHRS: move fly_forward flag to front end 
This same flag is requested by the DAL so AN_NavEKF2 and AP_NavEKF3 can
use it in their estimates - so AP_AHRS_DCM accessing it via the same
mechanism is not out-of-shape

Peter Barker f557d41145 AP_AHRS: rotate quaternions into vehicle body frame 
DCM was having it both ways depending on whether it was
primary/secondary.

These are mostly uses for reporting, in which case you would expect the
quaternion to match the eulers.

Lucas De Marchi 831d8acca5 Remove use of PROGMEM 
Now variables don't have to be declared with PROGMEM anymore, so remove
them. This was automated with:

    git grep -l -z PROGMEM | xargs -0 sed -i 's/ PROGMEM / /g'
    git grep -l -z PROGMEM | xargs -0 sed -i 's/PROGMEM//g'

The 2 commands were done so we don't leave behind spurious spaces.

AVR-specific places were not changed.

Gustavo Jose de Sousa 54d5277842 AP_AHRS: standardize inclusion of libaries headers 
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.
